Abstract: A parallel rendering method was presented with PC clusters in order to render massive aircraft CAD models in real time with high resolution. PC clusters were used for sort-first based rendering, BVH tree was built for efficient frustum culling, DID screens were utilized for high resolution display. In addition, multi-CPUs were exploited for thread based parallel out-of-core paging, frustum culling, BVH tree building and rendering. The experimental results show that by this parallel rendering PC clusters consists of 15 PC nodes, aircraft CAD models with 1.7 million of triangles can be rendered in real-time with resolution of 6800* 2304 pixels.

Key words: massive CAD models, parallel rendering, cluster, multi-threads
